Description

本発明は、スレート屋根材を取り外さずにこの上に金属屋根材を葺設するスレート屋根材の葺替用金属屋根材及びそれを用いたスレート屋根材の葺替工法に関する。   The present invention relates to a metal roof material for replacement of a slate roof material in which a metal roof material is installed on the slate roof material without removing the slate roof material, and a replacement method of the slate roof material using the metal roof material.

従来から、古くなったり、痛んだりしたスレート屋根材を補修する場合、古くなったスレート屋根材を屋根から剥がし、新たに新規のスレート屋根材を施工していた。   Conventionally, when repairing an old or damaged slate roof material, the old slate roof material is peeled off the roof and a new slate roof material is newly constructed.

ところが、上記従来の方法では、一旦既設のスレート屋根材を剥がし、再び新規屋根材と交換するのに、その施工に要する期間が長期間になるだけではなく、葺替工事期間中は剥がされた屋根には屋根材がないために、風雨を防ぐ養生が必要であった。また、剥がしたスレート屋根材は不燃性であり、大量に発生するとその処理が大がかりとなり葺替工事のコストが増加し、加えて、環境に悪影響を及ぼすという問題があった。   However, in the above conventional method, once the existing slate roofing material is peeled off and replaced with a new roofing material, not only does the construction take a long time, but the roof that has been peeled off during the replacement work period. Because there is no roofing material, curing was necessary to prevent wind and rain. Further, the peeled slate roofing material is incombustible, and when it is generated in large quantities, the treatment becomes large and the cost of replacement work increases. In addition, there is a problem that the environment is adversely affected.

このような葺替用金属屋根材を用いて既設スレート屋根を葺き替える手順について、図４〜図１２に基づいて説明する。   A procedure for replacing an existing slate roof using such a replacement metal roof material will be described with reference to FIGS.

先ず最初に、既設のスレート屋根材２の上面を覆い隠すようにして葺替用金属屋根材を載置する。次に、金属屋根材１の前端部の垂下片１１を下段側スレート屋根材２の軒側端縁２１に係止し後端部の立上片１２を上段側スレート屋根材２の軒樋端縁２１に当接して、固定具３を介して金属屋根材１とともに下段側スレート屋根材２を野地板等の屋根下地４に固着する。この作業を横方向に隣接する下段側スレート屋根材１の上にも順次行う。なお、符号５は屋根下地４の軒先に固定される軒瓦であり、この軒瓦５に最下段のスレート屋根材２の軒側端縁が載置されるようになっている。   First, the replacement metal roof material is placed so as to cover the upper surface of the existing slate roof material 2. Next, the hanging piece 11 at the front end of the metal roofing material 1 is locked to the eaves side edge 21 of the lower slate roofing material 2, and the rising piece 12 at the rear end is fixed to the eaves edge of the upper slate roofing material 2. 21, the lower slate roof material 2 together with the metal roof material 1 is fixed to the roof base 4 such as a field board through the fixture 3. This operation is sequentially performed on the lower slate roofing material 1 adjacent in the lateral direction. In addition, the code | symbol 5 is an eave roof tile fixed to the eaves edge of the roof base | substrate 4, and the eaves side edge of the lowest slate roofing material 2 is mounted in this eave roof tile 5. As shown in FIG.

下段側スレート屋根材２への金属屋根材１の葺設が終了してから、上段側スレート屋根材２の軒側端縁２１に当接している下段側金属屋根材１の立上片１２を上段側金属屋根材１の垂下片１１で係止した状態で上段側スレート屋根材１の上面に載置固定する。この作業を順次横方向及び流れ方向に逆らって頂上へと行う。   After the installation of the metal roofing material 1 on the lower slate roofing material 2 is finished, the rising piece 12 of the lower metal roofing material 1 that is in contact with the eaves side edge 21 of the upper slate roofing material 2 is The upper metal roofing material 1 is placed and fixed on the upper surface of the upper metal roofing material 1 while being locked by the hanging piece 11. This operation is sequentially performed to the top against the lateral direction and the flow direction.

図９〜１２に示すように、左手側の金属屋根材１の被重ね部１３に、右手側の金属屋根材１の重ね部１４が重ねられ、左手側の金属屋根材１の切欠部１５に、右手側の金属屋根材１の垂下片１１の左端部が嵌まり込んでいる。
従って、前端部の垂下片１１と後端部の立上片１２は重ね部分において重なることがないから横向に施工して行っても、前方に徐々に段違いにはみ出すことがなく、前端部の並びが直線状に仕上がる。 As shown in FIGS. 9 to 12, the overlapped portion 14 of the metal roofing material 1 on the right hand side is overlapped with the overlapped portion 13 of the metal roofing material 1 on the left hand side, and the cutout portion 15 of the metal roofing material 1 on the left hand side is overlapped. The left end portion of the hanging piece 11 of the metal roof material 1 on the right hand side is fitted.
Accordingly, the hanging piece 11 at the front end and the rising piece 12 at the rear end do not overlap at the overlapping portion, so even if the construction is performed in the horizontal direction, it does not gradually protrude forward and the front ends are arranged. Is finished in a straight line.

上述のように、葺替用金属屋根材１でスレート屋根材２を覆い隠すことにより葺き替えられたスレート屋根は、既設の棟瓦等の役物と違和感がなく外観上が見栄えよく葺設された構造のものが得られる。葺設した金属屋根材の上を歩いても、凹むことがない。
〔比較例１〕 As described above, the slate roof that has been replaced by covering the slate roofing material 2 with the replacement metal roofing material 1 has a structure in which the appearance of the slate roof is not discomforting with the existing building tiles and the like, and the appearance is attractive. Things are obtained. Even if you walk on the erected metal roof material, it will not dent.
[Comparative Example 1]

従来の方法で用いられる金属屋根材を使用して実施例１と同じ既設のスレート屋根材の上に重ね葺き施工した。この金属屋根材は、鋼板厚みが実施例１と同等の０．３ｍｍであるが、その形状は、図１３に示すように既設スレート屋根材２ａと略同一のピッチの台形状の山部が形成されてたものである。金属屋根材１ａの山部は１山おきに支持ボルト３ａを使用して屋根下地に固定されているが、スレート屋根材２ａの傾斜部のみで支持される構成であるため、施工中に歩行により金属屋根材１ａの山部や山谷に凹みが生じた。
〔比較例２〕 Using the metal roofing material used in the conventional method, it was overlaid on the same existing slate roofing material as in Example 1. This metal roofing material has a steel plate thickness of 0.3 mm, which is the same as in Example 1, but the shape thereof is formed as trapezoidal peaks having substantially the same pitch as the existing slate roofing material 2a as shown in FIG. It has been done. Although the mountain part of the metal roofing material 1a is fixed to the roof base using the supporting bolt 3a every other mountain, it is a structure supported only by the inclined part of the slate roofing material 2a. The metal roofing material 1a has dents in the peaks and valleys.
[Comparative Example 2]

比較例１で用いた金属屋根材の鋼板厚みを０．８ｍｍとした以外は比較例１と同じである。この場合は、施工中に歩行により金属屋根材の山谷に凹みは生じなかった。   Comparative Example 1 is the same as Comparative Example 1 except that the steel sheet thickness of the metal roofing material used in Comparative Example 1 is 0.8 mm. In this case, there was no dent in the valley of the metal roofing material due to walking during construction.

なお、上記実施例１及び比較例１、２の方法で得られた葺替構造の屋根について、図１４に示すような評価装置で降雨時の騒音レベルを測定し発音性の評価を行った。
発音性の評価方法としては、施工した屋根材ｆの鉛直上方２ｍの位置に散水装置ｄを設置して、この散水装置ｄから散水して降雨量１００ｍｍ／時間相当の降雨を人工的に再現し、前方２ｍの位置で騒音計ｅにて騒音レベル（音圧：単位ｄＢ）を計測する方法を採用した。その結果は表１の通りで、比較例１、２ではいずれも耳障りな音を発したが、実施例１の場合は既設スレート屋根材単独の場合とほぼ同等の騒音レベルであった。 In addition, about the roof of the replacement structure obtained by the method of the said Example 1 and the comparative examples 1 and 2, the noise level at the time of rain was measured with the evaluation apparatus as shown in FIG.
As a method of evaluating sound generation, a watering device d is installed at a position 2 m above the constructed roofing material f and water is sprinkled from the watering device d to artificially reproduce rainfall equivalent to 100 mm / hour of rainfall. Then, a method of measuring a noise level (sound pressure: unit dB) with a sound level meter e at a position 2 m ahead is employed. The results are as shown in Table 1, and both Comparative Examples 1 and 2 produced harsh sounds. However, in Example 1, the noise level was almost the same as that of the existing slate roof material alone.

以上、本発明の実施の形態を図面により詳述してきたが、具体的な形態はこの実施の形態に限られものではなく、本発明の要旨を逸脱しない範囲における設計の変更等があっても本発明に含まれる。
例えば、上記実施の形態では、四辺で互いに向き合った角隅に切欠部１５、１６を形成したが、右端部の被重ね部１３における前後端部の垂下片１１と立上片１２にそれぞれ切欠部を形成してもよい。 The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific embodiment is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. It is included in the present invention.
For example, in the above embodiment, the notches 15 and 16 are formed at the corners facing each other on the four sides, but the notch portions are respectively formed on the hanging piece 11 and the rising piece 12 at the front and rear end portions in the overlapped portion 13 at the right end portion.
